PAUL IGATZ, OF ELIZABETH, 'NEW JERSEY.

BOAT AND VESSEL.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed March 24, 1909. Serial No. 485,424.

To all whom it may concern:

Be it known that I, PAUL IGATZ, a citizen of the United States, and resident of Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Boats and Vessels, of which the following is a specification.

The present invention relates to vessels, and more particularly to an auxiliary power system thereof, which is independent of the power plant actuating the propelling means, and may be used for producing power for any desired purpose.

Broadly speaking, the invention consists of a plurality of passages or tubes leading through and below the water line of the vessel to a plurality of penstocks, in which there are arranged a plurality of turbines or water wheels, and from which penstocks lead a plurality of passages or tubes at lower levels than the aforementioned passages into the surrounding water, whereby the flow of water through the said passages, caused by the movement of-the vessel, will actuate the turbines or water wheels.

The invention is illustrated in the accompanying drawings, in which- Figure 1 is an elevation, partly in section, of a vessel equipped with the device embodying the main features of the invention, Fig. 2 is a section taken on line 2, 2.

of Fig. 1, and Fig. 3 is a plan view of the vessel.

In the drawings, the numeral 4 indicates the hull of a vessel of any desired type. This vessel may be propelled by screws 5, 5, rotated by any desired source of power, such as, for instance, a steam engine, in the usual manner. A plurality of tubes, in the present case two tubes, 6 and 7 lead from the bow part of the vessel and below the water line to penstocks 8 and 9, respectively, in which are arranged turbine-wheels 10 and 11, respectively, in a plane below the plane of the inlets l2 and 13 of the tubes 6 and 7, respectively. In the tubes 6 and 7 are arranged valves 6 and 7 or their equivalents, for closing and opening communications between the surrounding water and the penstocks. From these penstocks lead passages or tubes 14 and 15, preferably, through the bottom of the vessel, establishing thereby communications between the penstocks and the water surrounding the vessel. It will be observed from the examination of the drawings, that the passages or tubes 6 and 7 are slightly inclined and lead to the upper ends of the penstocks, while the tubes 14 and 15, which are in a similar manner slightly inclined, lead from the lower ends of the penstocks through the bottom of the vessel to the surrounding water.

It is obvious that the turbines may be of any suitable type and construction, and the shafts of their rotors may be provided with any suitable gearing, transmitting power to any suitable driven member. In the case illustrated in the drawings, the shafts 16 and 17 of the turbines 10 and 11, respectively, carry bevel gears 18 and 19, respectively, in mesh with bevel gears 20 and 21, respectively, the shafts 22 and 23 whereof are connected in any suitable manner to driven parts, wherefrom the power may be taken off, or may carry thereon the armatures of dynamos for a well known purpose.

It will be easily seen that there may be provided as many passages and penstocks as shall be required to meet the particular purpose, it being, however, essential that the inlets of the tubes, leading to the penstocks, shall be arranged in such a manner that a flow of water will be caused through the same as the vessel is propelled by its propelling means. For instance, further penstocks 24 and 25 may be provided, to which lead tubes 26 and 27, respectively, the inlets 28 and 29 whereof are arranged in such a manner that water, which naturally flows from the bow part of the vessel to the stern part when the vessel is propelled, will be caused to enter said passages. Outflow passages or tubes 80 and 31 lead from the penstocks, in a manner hereinbefore described, through the bottom of the vessel, either independently or the said tubes 30 and 31 may be united by a common outflow tube 32.

The operation of the device described is as follows: As the vesel is propelled through the water, a flow of water will be caused through the inlet and outlet passages, hereinbefore described, and the head of the water, due to the diiference of levels of the inlet and outlet tubes of the penstocks, will actuate the turbines in a well known manner. The power may be transmitted from the turbines to the parts intended to be driven in any suitable manner.

What I claim is:

The combination with a vessel, of a plurality of cylindrical penstocks arranged therein, turbine shafts in said penstocks, turbine-wheels carried by said shafts and operating independently of the power device actuating the propelling means of said vessel, a plurality of inlet tubes leading below the water-line of said vessel and from a higher level to the upper ends of said penstocks and causing communications between the surrounding water and sa d penstocks, a

10 plurality of outlet tubes leading from the lower ends of said penstocks into lower levwater is caused when said vessel is propelled by its propelling means to act by its vev locity and head.-

Signed at Elizabeth, in the county of Union and State of New Jersey, this 19th day of March, A. D. 1909.
